Answer:
y=2x−7
Step-by-step explanation:
so
formula is (
y
1
−
y
=
m
(
x
1
−
x))
m is the slope
-1-y=2(3-x)
add 1 to both sides
−y−1+1=−2x+6+1
−y=−2x+7
divide both sides by -1
y=2x−7
Hope this helps

Answer: She should blend 98 lbs of high-quality beans.
She should blend 72 lbs of cheaper beans
Step-by-step explanation:
Let x represent the number of pounds of high quality beans that she should blend.
Let y represent the number of pounds of cheaper beans that she should blend.
She needs to prepare 170 lbs of blended coffee beans. This means that
x + y = 170
She plans to do this by blending together a high-quality bean costing $4.75 per pound and a cheaper bean at $2.00 per pound. The blend would sell for $3.59 per pound. This means that the total cost of the blend would be 3.59×170 = $610.3. This means that
4.75x + 2y = 610.3 - - - - - - - - - -1
Substituting x = 170 - y into equation 1, it becomes
4.75(170 - y) + 2y = 610.3
807.5 - 4.75y + 2y = 610.3
- 4.75y + 2y = 610.3 - 807.5
- 2.75y = - 197.2
y = - 197.2/-2.75 = 71.9
y = 72 pounds
x = 170 - y = 170 - 71.9
x = 98.1
x = 98 pounds
Answer:
200 x 100 = 2000, he might not
Step-by-step explanation:
This is a problem of doubling time, the general formula for doubling time is
N = A(2)^( t /d)
where N is the future wind generating capacity in thousand MW
A is the initial wind generating capacity which is 95,000 MW
d is the time it will double, which is 3 years
t is the time in the future in years
N = 95(2)^( t / 3) is the formula for t<span>he continuous growth rate and give a formula for wind generating capacity W W (in thousand megawatts) as a function of t t , the number of years in the future</span>
